I'm able to view reports and access everything. However, I'm not trying to log in. Maybe that's the mechanism that's down.

Try a different browser. Ya never know, it might work.

Has been OK here in the UK

Actually, I wasn't trying to login, just access the page that I keep open. I can access analytics OK. I tried logging out of my google acc and back in but that didn't change anything, Also tried a different browser.

Have you tried the app?

I just got that message myself, trying to take a peek. They must be sorting out what GDPR slot to put people in based on their location? I don't depend on AdSense that much, I'll check back in a few days.

Ha... this part "I'll check back in a few days" proves this part "I don't depend on AdSense that much"

OK so it is over 48 hrs now. Realy getting withdrawl symptoms!

Seeing the same message on a friend's account but I am able to view stats fine in the Android app.

Normal service has just been resumed after a little over 4 days! However, as other mentioned, the mobile version did still work.

Just wondering. Did you, at any time during the time period, SHUT DOWN your computer, router/modem and then try again?

A few of my acquaintance seem to have run into "constant connection" problems wherein the logged in page they keep "active" for weeks and months at a time suddenly failed and no number of log outs and logging back in did a thing. In the few cases I was aware and made the suggestion, the next log in was immediate and functional.

Just sayin' ... when in doubt, REBOOT!

Tried rebooting the computer, used a different browser, and tried a different computer with no effect. Didnt reboot the router but we may have had a short power cut (we get those now and again) that would have rebooted it at some time. Perhaps a power cut sorted the problem.
